(Compute the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes the area and volume using the following formulas: area = radius * radius * π volume = area * length #Beginner In gcc c++ compiler using namespace std; #include<iostream> using namespace std; int main() { const double PI = 3.14159; double radius , length ; cout<< "enter the radius of cylinder :" ; cin>>radius; cout<< "enter the length of cylinder :" ; cin>>length; double area = radius * radius * PI ; double volume = area * length ; cout<< " \n area of cylinder is :" <<area<<endl; cout<< " \n volume of cylinder is :" <<volume<<endl; return 0; } copy Output enter the radius of cylinder :4 enter the length of cylinder :6 area of cylinder is :50.2654 volume of cylinder is :301.593 [Program
(Geometry: distance of two points) Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them.The formula for computing the distance is √ (x2 - x1)²+ (y2 - y1)² . Note that you can use pow(a, 0.5) to compute √a. #Beginner In gcc c++ compiler using namespace std; #include<iostream> #include<cmath> using namespace std; int main() { float x1,y1,x2,y2; cout<< "Enter x1 and y1 :" ; cin>>x1>>y1; cout<< "Enter x2 and y2 :" ; cin>>x2>>y2; float distance=pow((pow(x2-x1,2))+pow(y2-y1,2),0.5); cout<< "The distance between the two points is :" <<distance; return 0; } copy Output Enter x1 and y1 :1 9 Enter x2 and y2 :3 -5 The distance between the two points is :14.1421 [Program finished] Need of Programmer Need of Programmer
(Area and perimeter of an equilateral triangle) Write a program that displays the area and perimeter of an equilateral triangle that has its three sides as 9.2, using the following formula: area = 1.732 * (side)²/ 4 perimeter = 3 * side #Beginner In gcc c++ compiler using namespace std; #include <iostream> using namespace std; int main() { float side = 9.2; float area = 1.732 * side * side / 4; float perimeter = 3 * side; cout << "area of the triangle is : " << area << endl; cout << "perimeter of triangle is : " << perimeter; return 0; } copy Output area of the triangle is : 36.6491 perimeter of triangle is : 27.6 [Program finished] Need of Programmer Need of Programmer
